The AD7898AR-3REEL is a 12-bit analog-to-digital converter (ADC) designed primarily for monitoring battery-powered systems. The device may operate as a stand-alone 12-bit ADC, but is also capable of interfacing with a microcontroller and other complex systems. The ADC offers several features such as programmable input ranges, integrated voltage reference, high accuracy, and low power operation.

The AD7898AR-3REEL is a monolithic integrated circuit comprised of low power input channels, analog-to-digital conversion, and voltage reference. The input channels are programmable with bipolar, unipolar, and differential input ranges. This allows the ADC to be configured for different input signals including thermocouples and strain gauge measurements. The voltage reference is internally trim-able to allow for accurate conversion of the input signal to a digital output.

The ADC also features a low power operation. The standby current is less than 5 microamps and quiescent current is less than 140 microamps. This allows the device to have a long lifetime when powered by lithium batteries or other power sources. The device also has a low offset of 0.5mV and an isolated voltage reference output.

The AD7898AR-3REEL can be programmed with a serial interface or through servo commands. The serial interface allows the user to program the device with the voltage range, register read/write commands, and data read/write commands. The servo commands allow the user to set the device up as a stand-alone unit. The device can also be configured to read/write multiple channels in a single cycle.

The AD7898AR-3REEL operates from a 2.7V to 5.5V power input. The device is also capable of interfacing with various microcontrollers. This allows the user to interface the device with a microcontroller for complex data acquisition and control applications such as power monitoring and test equipment.

The AD7898AR-3REEL is capable of sampling up to 30kSPS and resolution of up to 12 bits. This allows the device to be used for precision measurements as well as fast data acquisition. The device also has a wide operating temperature range of -40C to +85C so it can be used in extreme environments.

In summary, the AD7898AR-3REEL is a 12-bit analog-to-digital converter designed for low power operation in battery-powered systems. It is capable of sampling up to 30kSPS, resolution of up to 12 bits, and a wide operating temperature range. Additionally, the device can be configured with bipolar, unipolar, and differential input ranges as well as serial and servo commands. This makes the AD7898AR-3REEL an ideal choice for precision measurements in demanding environments.
